The bear pajamas she wears were a demand from character animation director Takahiro Kishida. Though bears are a trademark of the Konaka brothers, Chiaki Konaka first opposed the idea. Director Nakamura then explained how the bear motif could be used as a shield for confrontations with her family. It is a key element of the design of the shy "real world" Lain. When she first goes to the Cyberia nightclub, she wears a bear hat for similar reasons. The pajamas were finally considered as possible fan-service by Konaka, in the way they enhance Lain's nymph aspect.

His designs are instantly recognisable, I like his style. I'm surprised to see that he even did work on Lain and Madoka, although those can't have been major contributions (those series had other main character designers).
